Can we overhaul the RSS feeds

[ckipp01]

This stems from a comment on reddit and when looking into the RSS feeds that we have:

• https://www.scala-lang.org/feed/index.xml
• https://www.scala-lang.org/feed/blog.xml

While maybe it could be argued it's nice to have 2 separate feeds, I think it's just easier to have one and pipe everything into it. Right now the blog one is only getting fed things that fall into the blog category. The other one only gets things that are coming from the news category, but nothing there has been posted in years. I find the way this is set up to be quite confusing. The distinction between announcement and news is unclear to me and I don't even think it's necessary.

This might be a good opportunity to overhaul the categories and fix the rss feeds at the same time. I see this was also brought up before in the past in #1006 and #849.

Thoughts?

I guess you know from reading #849 and #1006 that I'm strongly in favor of radically simplifying this bewildering mess.
